Samba AD management from Windows
To manage Samba4 AD form Windows you need to install Windows Remote Server Administration Tools (RSAT). Before you begin, make sure that the domain administrators have administrative rights to control your computer. (To give any user administrative rights in Windows XP Pro, right click My Computer, select Manage→ choose Groups→ double click Administrators and add members from domain into the member list. When you add members from Active Directory, it will prompt you to enter an Active Directory username and password).
The above tools can be download from UCLV Softlib Repository
Administration Tools Pack & Support Tools
Group Policy Management Console
This is primarily useful when you have larger installs and are managing many machines. You may need to download the .NET Framework first.
